TYPE-WRITING MACHINE.

Specification of Letters Patent.

Patented July 19, 1910.

Application filed February 24, 1909. Serial No. 479,807.

To all whom it mag concern:

Be it known that I, ALFRED LINDENBERG, merchant, a subject of the German Emperor, and resident of Moscow, in the Empire of Russia, with the post-oliice address of .Mjasnitzkaja 36, Hans Eibuschitz, have in vented new and useful Improvements in T ype-Writing Machines, of which the following is a specification.

It is a known practice to divide the type on the type-bars of a typewriting machine into separate groups, the several groups of type belonging to different systems of characters, so that by means of shifting devices the characters of one or other system can be brought into action when the keys are struck.

The novelfeature of the present invention consists in the platen itself being adapted to be adjusted, relatively to the type, both from group to group and also within each group. The type are mounted in any customary manner, so that the transition from one system of character to another is effected with ease and Without any tendency to jam.

The subject of the invention is illustrated as a typical example in the accompanying drawing.

Figure 1 is a view of the carriage with the platen; Fig. 2 is a section along the line A-B of Fig. 1; Fig. 3 a section along the line (l-JJ of Fig. 1; Fig. 4 a section along the line EF of Fig. 1, and Fig. 5 illustrates the shifting of the platen roller in a diagrammatic manner.

The roller frame 3, supporting the platen roller 1, direct, is adjustably mounted in a. shift frame 2, and is adapted to be fixed in position by means of hooks 9 engaging in holes l0, ll of the frame 2. By means of a spring 1.2 which pressesgzonstantly against a handle 13 01 the hook 9 the latter is held in con stant engagement with the frame This frame 2 in turn is adjust-ably mounted in the frame 14:, in which it can be adjusted vertically in the usual manner by means ot' the rollerlo and lever 16. In addition this frame 14% is shifted forward longitudinally in the known manner each time the keys are struck. v

To prevent jamming between the rollerframe 3 and the shiftiraine 2, a parallel guide, consisting of racks 17 and pinions 18 in the usual manner, is interposed so that all skewing and jamming of the frame 3 is prevented.

The types are arranged on the type-bars (Fig. 5) in two groups 19, 20, each comprising three characters, for example, a capital letter,-small letter and a number relating to one language. For instance, the group) may be formed of German characters and group 20 of Russian characters.

lVhen it is desired to write anything in German, the roller carrying the paper re mains in the position shown in Figs. 1 1

The shifting of the roller within the limits of the group 19 of characters is effected in the usual manner by means of the roller 15 and lever 16, so that large and small letters and numbers can be used alternately. If a Russian word or sentence has to be written, pressure is applied to the handle 13 so that the hooks 9 swing out and the laten and its frame can be pushed downwar until the hooks 9 catch in the holes 11 and stop the frame 3 again. The platen now assumes the position 11 of Fig. 5, so that when the keys are struck the type group 20 eolnes into operation. The shifting within the limits of this group, for obtaining large or small letters or numbers, is eli'ecteil in the same way by means of the roller 15 of the lever 16 and the same shift mechanism as in the former case. If German is to be written again, the operation is reversed until the paper roller returns into the position I of Fig. 5.

It will be evident that the shifting operation can he PQIfOi'Il'lQd without any great trouble and loss of time. Of course, three groups of characters may also he used. in

place of two; and furthermore, it is not necessary that all the characters in any group should belong exclusively to one language. For example, all the eharz'ietcrs of all the groups may belong to the same for shifting the platen from one.
